The wizard runs when you create a new combo box, while the 'Use Wizards' button in the Toolbox is depressed.
'Use Wizards' is the button at the top right of the toolbox (in Access 2000) which has a 'magic wand' symbol on it. If you hover the mouse over this button, the Tool Tip says 'Control Wizards'.
Click this button, and make sure it is in the 'depressed' position, then create your combo box. The wizard will then run for you.
